structure and an improved finish doing away with overlapping riveted or welded joints and providing the window openings withintegral pressed sash members or glass supporting flanges.

Having this general object in view the in-.

vention contemplates the construction. ofthe side sheathing of a car from unit sections corresponding individual extent to the window opening divisions longitudinally of the car and vertically extending the full height of the car side, theline of junction between the several sections being either along the medial vertical line of the side posts between the window opening or along the medial line of the window openings themselves. In either case the opening is defined by an integral flange inturn'ed from the sheathingun'it and the side post of the car-is confined-between the adjacent flanges of contiguous openings, the side post and anges serving formutual support and'thus adding further rigidity to the structure as a whole. I

In order that the structural features of the inventionmay be readily understood I have in the accompanying drawings illustrated the same as embodied in two slightly different forms.

In these'drawings, Figure 1, is a side elevation of a car side showing an I-shaped unit section; Fig. 2', is a vertical section on the line 2-2 of Fig. 1;; Fig. 3, is a detail section upon an'enlargedscaleion the line 33 of Fig.1; Fig, 4, is a viewsimilar to Fig.

1, but illustrating a rectangular unit section; Fig. 5, is a vertical sect1on-on the hue of Fig.4; and Fig. 6 is a horizontal section on'the line 66 of Fig. 4.

these drawings and having particular reference to Figs. 1, 2 and 3, the side sheath .55 ing of the @car is shown as made up of I shaped .unit sections which for convenience may be designated as comprising each a lower port on 11 below the belt rail of the car, a panel portion 12 extending vertically between the window openings and a letterboard 'portlon 13 above the window openings. In thls form of construction each of the units is of'a general I-shape and embraces vertically the full height of thecar and longitudinallv the adjacent halves of two window openings 14,14.

The rectangular sheet of metal from which the sheathing unit is to bemade is by apress provided upon opposite edges in those portlons corresponding to the adjacent halves of the window openings with a depression in the shapelof a. panel of which the lower portion is ofl' set in a plane parallel to the general plane of the sheet. tion is then punched out at a slight distance from its edge so asto leave an opening'having a margin. It will thus be seen that the The oflset porunit section provides on opposite edges adjacent halves of two contiguous window openingsdefined by the inturned continuous flange 15 and the offset continuous flange 16 extending across the bottom of the opening to form a sill and along the sideand over the top of the opening to form the casing. It will also be seen that when the car side is built up of: unit sections joined by welding or in other suitable manner along the vertical line corresponding to the medial line of the opening,'the entire window opening is defined by-the inturned continuous flange 15 and the offset continuous marginal flange 16. j

The marginal flange 16 may-serve as a sash member or support'for the glass 17 A packing strip 18 of rubber, felt or the like is arranged between the edge of the glassl? and the flange 16 while a filler block 19 of substantially the width of the glassand packing strip surrounds the outer edge of the glass and rests upon the flange 16. A glazing strip 20 overlies the packing strips 18 and the filler block 19 in opposition to the offset flange 16 and is clamped upon the packing strip and filler block .by means of cla-mpmg screws made up of male and female members 21 and 22 having a countersunk bearing upon the glazing strip and the flange respectively. By this means the glass is held firmly in position and the entrance of dust or moisture efi'efitually precludedwhile 45 {ftheconstruction and forming together a very eral I-shape and each embracing t the glass is easily removed for renewal in case of damage.

The sheathing units are secured by riveting or in other approved manner ,to the side sill 23 and the side plate Y24: and also to the side posts 25 which latter occupy a position immediately to the rear of the panel portion 12 of the sheathing and are of such widthas to snugly fit within the space between the adjacent flanges 15 of contiguous window openlngs 14. In this way the flanges 15 of the sheathing coiiperate with the posts 25 to.

mutually support each other and contribute to increase the rigidity and strengthfof the structure as an entirety.

The embodiment shown in Figs. 4, 5 and 6 differs from that already described in that, instead of the sheathing units bein of a genhe half of contiguous window openings, they are of general rectangular shape joined along the medial vertical line of the side post and each embraces an entire window opening. In this.

form of construction the rectangular: sheet of metal is in its upper central portion formed with a depressed panel and the oflset panel is punched out along its top and side edges and at a distance from its bottom edge so as to provide along the top and sides the inturned flange 27 and to leave an offset bottom portion 28, the upper margin of which ortion 28 is then bent inwardly to form a orizontal sill 29.

The several sections are arranged with their'meeting edges abutting along the medial line of the side post 30 whichpost, as in side posts interposed between and the form of construction previously described, is of a width to fit snugly between the flanges 27 of contiguous window openings. The sheathing units are as in-the former case suitably secured to the side posts andaboye and below to the side plate 31 and side sill 32, the flanges 27 of the sheathing units and-the side post 30 mutually support ing each other to lend additional rigidity to to be'understood as limitingmyself to the particular construction shown.
